"LANG=x your_app" will start a program with a different language
settings. But beware of LANG interaction with LC_ - LC_ overrides LANG.
Use LC_ALL instead of LANG if you want to be 100% sure, but this can be
undesirable... For example if you want to start application with english
GUI, but have german sorting and dates, use "LANG=en_US.UTF-8
LC_COLLATE=de_DE.UTF-8 LC_TIME=de_DE.UTF-8 your_app"
